About the UK Holiday Entitlement Calculator
This UK holiday entitlement calculator works out how much statutory annual leave you are entitled to under the Working Time Regulations. For a fixed number of days a week it applies the 5.6-week rule — 5.6 × days worked, capped at 28 days. For irregular-hours and part-year workers it applies the 12.07% accrual rate to the hours you actually work, which is the method for leave years starting on or after 1 April 2024.
It is built for part-time staff checking their contract, workers on zero-hours or term-time contracts, and anyone starting or leaving a job part-way through the leave year. Switch on the part-year option, enter the leave year start date and the dates you are employed, and it pro-rates your entitlement by the days employed, subtracts the leave you have already taken and tells you how many days are owed — and roughly what they are worth in your final pay.
The figures are the legal minimum. Your contract may give more (many employers add bank holidays on top), and statutory leave can include bank holidays. Holiday pay itself should reflect normal pay including regular overtime; for the value shown here, the calculator simply divides your weekly pay by the days you work each week.
With the default inputs, the holiday entitlement is 28 days. Change any value above to recalculate instantly.

Formula and method
Almost every UK worker is entitled to 5.6 weeks of paid holiday a year. For someone working the same number of days each week that is 5.6 × days per week, with a statutory cap of 28 days, so a six-day worker still gets 28. Hours are the days multiplied by the length of a normal working day.
If you start or leave part-way through the leave year, this calculator pro-rates the full-year figure by the calendar days you are employed in that leave year. For irregular-hours and part-year workers in leave years starting on or after 1 April 2024, holiday accrues at 12.07% of hours actually worked — 5.6 weeks ÷ 46.4 working weeks — at the end of each pay period. Employers may round entitlement up but never down.

Worked examples
Full-time, five days a week
5.6 × 5 = 28 days, which is exactly the statutory cap. At 7.5 hours a day that is 210 hours. With no leave taken and £120 per day (£600 ÷ 5), the full entitlement is worth £3,360.
Part-time, four days a week
A four-day worker gets 5.6 × 4 = 22.4 days, or 168 hours at 7.5 hours a day. After 10 days taken, 12.4 days remain, worth 12.4 × £120 = £1,488.
Leaving on 30 June after taking 10 days
From 1 January to 30 June 2026 is 181 of the 365 days in the leave year, so the worker accrues 28 × 181 ÷ 365 = 13.89 days. Having taken 10, they are owed 3.89 days, worth about £466 in their final pay.
Irregular hours: 1,500 hours worked
Irregular-hours workers accrue 12.07% of the hours they work: 1,500 × 12.07% = 181.05 hours of holiday, which is about 24.1 days of 7.5 hours.
Frequently asked questions
How many days holiday is a part-time worker entitled to?+
Multiply the days you work each week by 5.6. Three days a week gives 16.8 days, four days gives 22.4 days. Employers can round up to a whole or half day but must not round down.
How much holiday do I get if I leave part-way through the year?+
You accrue a proportion of your annual entitlement for the part of the leave year you were employed. Your employer must pay you for any accrued statutory holiday you have not taken, usually in your final pay.
What is the 12.07% holiday rule?+
For leave years beginning on or after 1 April 2024, irregular-hours and part-year workers accrue holiday at 12.07% of the hours they actually work in each pay period. It reflects 5.6 weeks of leave out of the 46.4 weeks a year left to work.
Are bank holidays included in the 28 days?+
They can be. There is no legal right to paid leave on bank holidays on top of 5.6 weeks; employers can count bank holidays (8 a year in England and Wales, 9 in Scotland, 10 in Northern Ireland) towards statutory leave. Many contracts give them in addition.
What if I have taken more holiday than I have accrued?+
Your employer can only deduct overpaid holiday from your final pay if your contract or a written agreement allows it. Otherwise the extra leave is usually written off.
